Go out side on a clear night (hopefully the lights aren't too bright) and take your partner to stare out at the stars. Try to impress your partner by pointing out constilations. Guys: stand behind her and wrap your arms around her. As she continues to stare up, softly and slowly (if she's comfortable with this) lick the outer-most edge of her ear from bottom to top. She's sure to love it, and probably turn around for more!
